Have you found a resolution to your problem? I am having the
same issue, except I am trying to import and
other classes. I've posted a few times on here but can't
ever get a response.

I had a flex 2 app which worked great with flex data
services, but as of flash player 9.0.115 it doesn't want to work.
I've tried recompiling into flex 3 but all the packages and
classes are gone and I can't find any documentation on it

I have the same problem to you too. I look into the Flex 3
Language Reference and found the was gone and I
don't understand why adobe do that. Now I have a question "If I
can't invoke <mx:DataService>, how can I use data management
service of LiveCycle Data Service ES? and another question "If I
can't use data management service, what the benefit of using Flex 3
with LCDS because BlazeDS can do the same thing so why I have to
spend my money to this product?"

I use all of my energy to look for the answer of this but I
can only found the solution that use the Flex 2 so I guess that
LiveCycle Data Service is work well only on Flex 2, am I

<mx:DataService> fully supports Flex 3.

First go to your Flex project properties > build path >
properties, and make sure the fds.swc and playerfds.swc are
correctly linked - they should be if you used the project wizard

<mx:DataService> is under package

As for LCDS vs BlazeDS, LCDS supports data management
service. The data management service use a model oriented approach,
which is ideal for data driven, collaborative types of apps. It's a
bit difficult to explain in one sentence since there's nothing like
it on the market, but if you vest some time ramping up on it, it is
guaranteed to save you time down the road.

Thank you for your kindly reply Mr. Yang.

It's my fault from the installation phase of LCDS, I use the
J2EE server choice instead of JRUN. So when I start the new Flex
& LCDS Project and when I typed <mx:DataService> in
editor the error will wait for me.

When I reinstall with integrated JRUN option it work fine so
the next stage for me is what wrong with TOMCAT 6 for LCDS because
I already make the necessary process for install LCDS in TOMCAT
(involve install JOTM in TOMCAT 6). When I run the samples
application of LCDS in TOMCAT it has many error in backgound while
it work fine in JRUN but in the production deployment phase I want
to use TOMCAT.

I just want the "Data management Service" feature was
integrate in BlazeDS but I know that feature was the "main actor"
of LCDS so I hope Adobe will release the next BlazeDS with this
feature in it.

I feel very impressive for the DMS feature. It make me feel
the difference about "Web App." (or RIA). I fulfill my passion
about data handle software topic I don't ever seen something like
this one before. I just think that new policy about LCDS marketing
that stop Express Editor of this product will screen most people
from this greate product. So, I beg Adobe please release LiveCycle
Data Service ES 2.6 Express Editor and I will love you forever :).

Thank you again
